|    I wonder whether python compiler does basic optimizations to .py.

In general, the answer to such questions depends on the implementation and 
version thereof.  For CPython, you can look at bytecode with the dis module 
as another poster showed.

| a = 1 + 2

| a = 3

This was added to CPython in version 2.5, I believe.
